You say "network printer"? I just set this up on two different Dell Precision 5500 series laptops (mine, as a test, and the receptionist, who is the target user) both running Win11 and it worked fine - BUT the printer was direct-connected to those laptops via USB. JRE needs to be installed before you install the UPS helper app ... if not, you need to rerun the installer. Other than that, it just worked. I'm not sure this will work if the label printer is not direct-attached .... Answer from viswarkarman on reddit.com

UPS Thermal LP2844 Prints Half of UPS Label
Hmmm...have you tried setting up 4x6's in the print server properties as custom size(even though it's most likely a default) and selecting that in the driver? There seems to be a disconnect here. Printing from the browser always sucks but regardless this should work. Are you sure scaling/zoom/print footers and all that good stuff is not set when you go to print? What does the "print preview" look like? The printer could be over heating but eh, I'd try everything else first but check your darkness settings to ensure it's not too hot. I don't think this is the problem. When you hit feed does it feed a whole label to the gap? Might not like this but try a different browser for the sake of troubleshooting. Has to be a page size/setting thing. More on reddit.com

Trying to get a thermal printer to work with UPS Worldship 2018

You might have to install the printer as a zp450. I have had issues with ups worldship in the past when trying to use an "unsupported" printer that was identical to another zebra that they do support. I had to install it to the computer as if it were the supported one then it worked perfectly fine.

r/techsupport on Reddit: Has anyone had success printing UPS labels from ups.com website with Windows 11?
November 7, 2022 -

I know that Windows 11 changed a bunch things as far as printing goes, but ever since I upgraded to Windows 11, I can't print UPS labels from the ups.com site.

It usually goes:

-Install a Zebra label network printer as a printer

-Install Java

-Install the UPS applet

I have to use Edge to make it happen, but it works in Windows 10. The UPS applet runs a service that runs in the background with a 127.0.0.0 address. But when I print it says "no thermal printer found."

This is the page currently not showing support, but was wondering if anyone got it to work some other way.

Yes, I've tried all the dumb Chrome extensions. They are all scams and just point me to the website where I can buy their printer.

I'm chatting with UPS right now to see what they have to say.

Getting the labels in correct format

The FedEx & UPS APIs provide options to get thermal label specific types. You will beat your head on the keyboard trying to get PDFs to print properly on thermal printers.

Some common thermal types EPL/EPL2, ZPL/ZPLII. Most thermal printers will accept documents matching one of these types.

For Fedex something like this in your ShipRequest - This is using the FedEx WSDL for shipping.

RequestedShipment.LabelSpecification.ImageType = FedExShipService.LabelSpecificationImageType.ZPLII

And UPS - Building XML to post to the UPS service.

<LabelSpecification>
 <LabelPrintMethod>
  EPL2
 </LabelPrintMethod>
</LabelSpecification>

Printing the labels

You will need to essentially send "raw" data to the printer. I started with this article and adopted it to my solution. FedEx for example returns a byte array which contains the label information - I convert this to a string and then send to the printer.

'Convert from Byte Array to String
Dim enc As System.Text.ASCIIEncoding = New System.Text.ASCIIEncoding()
Dim strConverter As String = enc.GetString(<ByteArrayFromFedEx>)

There is also another thread on SO about this topic.

I used to work on UPS shipping systems and yes you can print using the thermal printers. You need the correct drivers installed to do this. Depending how you want to print will also determine how you need to install the printer (local or shared printer). HTH

r/printers on Reddit: UPS Thermal LP2844 Prints Half of UPS Label
March 4, 2025 -

Hello! I have been using this LP2844 for years and years but last fall it started only printing half of the label.

Some details:

I exclusively use the UPS thermal printer applet for shipping.

I use firefox for a browser.

Last fall the printer started disconnecting halfway through the print, reconnecting, restarting the print, then failing again. It fails at the same point over and over again.

I have tried guides for factory resetting but it made no difference.

I have installed the printer and UPS drivers fresh on two different machines with the same result.

It prints test pages and test labels just fine, It even prints UPS labels that I download (albeit the formatting is crazy). The problem only seems to occur when printing from the UPS thermal printer applet online.

I'm at my wits end with this. Any help would be appreciated.
